As a result, 10 taxa were selected for further study, 9 of which 

 will be discussed in this report. The winter flounder ( Pseudopleuronectes 

 americanus ) was the dominant finfish species in impingement (17.87Z), 

 and trawl collections (45,09%) and ranked second in entrainment 

 (10.96%). This species has been the subject of extensive investigations 

 detailed in the Winter Flounder Population Studies section. Anchovies 

 ( Anchoa spp.) ranked first among entrained larval taxa and second among 

 impinged taxa. Eggs of the cunner ( Tautogolabrus adspersus ) and tautog 

 ( Tautoga onitis ) were the two most abundant egg taxa entrained, but only 

 cunner was well represented in the other collections. Silversides 

 ( Menidia spp.), ranked fourth among impinged and trawled finfish, and 

 dominated the finfish catch from seines. Grubby ( Myoxocephalus 

 aenaeus ) , ranked third among impinged finfish as did American sand lance 

 ( Ammodytes americanus ) among entrained larvae. Sticklebacks 

 ( Gasterosteus aculeatus and G^. wheatlandi) , and Atlantic tomcod 

 ( Microgadus tomcod) , each contributed 5-8% to the impingement species 

 composition. Windowpane ( Scophthalmus aquosus ) , ranked ninth among the 

 impinged finfish and third among trawled fish. Salient life history 

 information on these taxa are summarized in Table 2. 



The selection criterion eliminated three finfish taxa that were 

 relatively abundant ( > 4%) in the trawl and seine programs: skates ( Raja 

 spp.), killifishes ( Fundulus spp.) and scup ( Stenotomus chrysops ) . 

 Since they were infrequently found ( < 1%) in impingement or entrainment 

 collections, these taxa were believed to be relatively unaffected by the 

 impingement or entrainment processes. Although northern pipefish 

 ( Syngnathus fuscus ) and sea robins ( Prionotus spp.) contributed more 

 than 2% to impingement and entrainment collections, respectively, they 

 were not selected for detailed analyses because of otherwise lov/ 

 abundances. 



Ammodytes americanus , American sand lance 



The taxonomy of sand lance has not been resolved and the numbers of 

 species found in the North Atlantic is questionable (Bigelow and 

 Schroeder 1953; Leim and Scott 1966; Scott 1972; Fritzsche 1978). 

 However, all specimens collected near MNPS were Ammodytes americanus .
